Description of Practice

To improve cost effectiveness in funding safety projects, Idaho Transportation Department used an innovative, data-driven program for safety analysis on roadways throughout the State. The project includes assessing 5 years of statewide crash records, diagnosing the priority locations to determine casual relationships between site characteristics and crash records, identifying recommended improvements, and conducting benefit-cost analysis to rank the recommended safety improvements.

Key Accomplishments and Results:

  • Utilization of the Highway Safety Manual (HSM) methodology to identify the highest priority locations for safety improvements
  • List of ranked safety improvement projects reflecting the most effective use of funding for safety projects
